A rectangle is generally defined as a quadrilateral with four right angles. No rectangle can have four different side lengths by that definition. Finding the area of such a shape is therefore impossible.
In order to find the perimeter of a 3D rectangle you must gather the lengths of the known sides, calculate the missing rectangular values, and use the formula for perimeter.
The rectangle is 12 units by 3 units.
A rectangle by definition has two pairs of sides with equal length. Since perimeter equals the length of all the sides. The equation for the perimeter of a rectangle could be thought of as: 2L + 2W = P Where L represents the length of one side of the rectangle and W represents the length of the adjacent (next to) side of the rectangle. If you know the length of one side and the perimeter, plug those values in as L and P and then solve for W. That will give you L and W which are the dimensions of the rectangle.
A rectangle with a perimeter of 36 units can have sides of any length as long as the lengths of the two differently-sized sides are equal to 18. For example, a rectangle with sides of 10 units and 8 units (don't forget to state what these units are, whether they are inches or centimetres or any other similar measurement), would have a perimeter of 36.
The dimensions of a rectangle are expressed as the extents of its sides in two orthogonal directions which are parallel to the sides. The lengths are usually unequal because otherwise the rectangle would be better known as a square.
Yes. The perimeter is a measure of the combined length of all the sides. If you double the lengths of the sides then naturally this will also necessarilychange the perimeter (it will double the perimeter).
A rectangle has four sides with two equal lengths.
It is the sum of the lengths of its 4 sides
How about a rectangle which is a quadrilateral with sides of different lengths
They both have 4 sides but of different lengths
Add together the lengths of the four sides; or add the lengths of the two different sides and then double it.
add the lengths of all the sides
Opposite sides are parallel and it has a breadth and width of different lengths
You can't tell the dimensions from the perimeter. There are an infinite number of different rectangles, all with different lengths and widths, that all have the same perimeter.
a rectangle (that is NOT a square) has 4 right angles and consecutive sides of unequal lengths.
Is it not a parallelogram in which the adjacent sides are of different/unequal lengths ?
